We divide 520780 by 51
Let's see how many times 51 fits into 520780.

Let's proceed to step 1:
When dividing 5 by 51, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 51

Moving on to step 2:
51 can be fit into 52 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 52, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 51

On to step 3:
10 divided by 51 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 10 leaves us with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 51

Let's proceed to step 4:
If we divide 107 by 51, we get 2 and a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 102.0
Subtracting 102 from 107 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 51

Step 5:
When dividing 58 by 51, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1021.0
The remainder is 7 after subtracting 51 from 58.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 51

Step 6:
51 can be fit into 70 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 10211.0
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
51 can be fit into 190 3 times, resulting in a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 10211.3
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
When dividing 370 by 51, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 10211.37
Subtract 357 from 370 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
130 divided by 51 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 10211.372
If we take 102 away from 130, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
The number 51 fits into 280 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 10211.3725
If we subtract 255 from 280, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 11:
When dividing 250 by 51, we get 4 with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 10211.37254
If we subtract 204 from 250, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 12:
51 can be fit into 460 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 10211.372549
Subtracting 459 from 460 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 13:
The number 51 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10211.372549
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 51, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 10211.37254901
Subtracting 51 from 100 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

The final result is 10211.37254901 with a remainder of 4.9e-08.
